ELECTRIC FIXTURE.

Application filed May 21, 1920. Seriali No. 383,084.

T0 all whom t may concern.:

Be it known that I, JOHN CU'rHBnRT, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Electric Fixtures, ofwhich the following is a specification.

lThis invention relates to electric fixtures.

It rela-tes more particularly to fixtures comprising electric socketsand insulating supports.

@ne of the objects of the invention is to provide an improved electricfixture.

Another object is to provide for the ready application of electricsockets to insulating supports.

Another object is to provide an insulating support to which an electricsocket may be readily attached.

Another object is to provide an improved socket attaching means for aninsulating support.

Other objects and advantages will appear from the specification andclaim.

An embodimentof the invention is illustrated in the accompanyingdrawing, wherein F ig. l is an elevation of a socket and support.

Fig. 2 is a partial sectional elevation of a socket and support, and

Fig. 3 is a longitudinal section of the socket holding eyelet beforeapplication to a support.

The iixture comprises, in general, an elet tric socket 5, an insulatingsupporting base 6 and means for holding the socket and base together.

Socket- 5 may be of the general type ordinarily used for receiving pluglamp sockets, connectors, etc., and may be of any desired size andornamental design. EX- amples of sockets which may be satisfaf torilyused are illustrated in my copending applications Serial No. 383,082;tiled Yfay 2l, i920, and Serial No. 833,085; filed lviay 2l, 1920. It isprovided with a rounded base end and an eXteriorly threaded projection7, having an opening for passing conductors into the interior. Thesocket illustrated is a plug receiving lamp socket.

Support or base 6 may be of any desired shape, size and constructionhaving a depression 6 to receive the base end of a socket. Ordinarilysuch supports are comtion 7.

The socket and support are assembled by screwing projection 7 intoeyelet 8.

Eyelet 8 may be made in the forni shown in Fig. 3 when ready to beattached to the support. The eyelet has a flange 9 at one end foroverlying the edge of the center opening through the support. The eyeletis inserted in the opening of the support `so that the outer surface offlange 9 is flush with the surface of the socket seat and then itsopposite end is riveted or spun over the other edge of the hole in thesupport.

The eyelet may be threaded either before or after it is inserted in andsecured to the support. It is preferred to thread the eyelet afterapplication to the support, since, then, the pressure required in theriveting or spinning operation does not tend to destroy the threads.

Providing insulating supports with a depression to receive the base endofthe socket and the threaded eyelets and the sockets with threadedprojections, as described, sockets and supports may be readily coinbinedto provide an improved fixture in which the end of the socket enters theinsulating support, being drawn thereinto by the threaded couplingmembers. This greatly strengthens the structure and improves itsappearance.

Having described my invention what I claim as new and desire to secureby Letters Patent is An electric fixture comprising a base and a socket,a rounded end on the socket and a rounded depression in the base, thetwo rounded portions having similar' contours, an internally threadednipple extending interiorly from the bottom of the depression and anexternally threaded projection on the socket, said nipple and projectioncooperating to draw the socket firmly into contact with the basedepression.

In testimony whereof I hereunto sub scribe my name.

JOEY` CUTI-IBERT.
